Abstract
A resin composition for automotive exterior applications, which comprises 50 to 70% by weight of crystalline propylene-ethylene block copolymer, 18 to 25% by weight of elastomeric polymer and 15 to 25% by weight of inorganic filler. The elastomeric polymer is a mixture of a copolymer rubber produced from ethylene and an α-olefin having 6 or more carbon atoms, an ethylene-α-olefin-nonconjugated polyene random copolymer, and a hydrogenated styrene-conjugated diene block copolymer. This resin composition exhibits excellent processibility, and possesses good balance of physical properties including flexural modulus, impact resistance, hardness and brittleness temperature. The moldings fabricated from it gives good appearance free of any remarkable flow mark or weld mark on the surface.
